Before spending any money on accessories, I'd turn the HD1850 in the direction of the stations you're looking for. If a deep-fringe, all-channel, roof mounted antenna is not seeing the desired signals, how on earth would any attic mounted antenna have hope of acceptable results?
FWIW, the differences in performance between the HD8200U and HD1850 are quite small, certainly not enough to expect one to overcome the added penetration loss of an attic/roof structure as compared to the other.

Sorry, maybe i wasn't clear. The hd1850 is outside pointed at new york and works great. The winegard will be pointed at philadelphia.
